Relitto LST 349 (WWII Landing Ship Tank)

About This Site
Relitto LST 349 is Ponza's signature wreck dive and the most-photographed site on the island, lying below the cliffs of Punta Papa on the north-west coast near Cala dell'Acqua. The USS LST 349, a roughly 100 m US Navy Landing Ship Tank, was driven onto the rocks and torn in two during a violent storm in the winter of 1943-44 while running between Anzio and Naples. The two sections now sit upright and roughly 50-100 m apart on a bright white sandy bottom: the stern at about 20-22 m and the bow, in near-perfect navigation trim and pointing north-west, at about 26 m. Preserved deck guns, cannon, holds still holding shipboard gear, and partial penetration make it a full two-dive site, usually enjoyed in the clear, current-free water off the point.

The wreck lies at the foot of Punta Papa on the north-west coast of Ponza, with the island headland and the Le Forna ridge to the south and south-east and the Cala dell'Acqua headlands to the east, so those sectors are well sheltered. The exposed window is the open Tyrrhenian to the north, north-west and west — the same NW-facing cliffs the storm drove the LST 349 onto. There is no ocean groundswell here, only wind-sea over fetch: the site takes it worst from a NW-N Mistral/Tramontana and, to a lesser reduced degree, a westerly, while Libeccio (SW) and Scirocco (SE) are largely blocked by the island. In summer the water is typically flat and current-free, but a sustained NW blow raises swell on the point and forces dives to be postponed.
